Abstract: Environmental quality of major food crops (rice, wheat and corn) producing areas were analyzed in Huai'an City, including Chuzhou District (M1), Qingpu District (M2), Hongze County (M3) and other 3 districts (counties), using fuzzy comprehensive evaluation method, and the contents of heavy metals (Pb, Cd, Cr, As, Hg) in soil and irrigation water in these areas were selected as evaluation factors. The result showed that the evaluation grades were classified into classⅠ, indicating the environmental quality of the soil and irrigation water reached the level of cleanness, which was quite necessary for the development of green food in these areas. Considering the existence of differences among counties and districts, the development of appropriate food products needs further analysis．
